OBD2 Port "Link Error"
What does "wasn't showing me anything" mean ? No connection to ground ? You could add a temporary ground wire from pin 4 to something solid metal in the cab.
Also did you check pin 7 resistance to ground ? Is the scan tool "known good" meaning it does work on other vehicles ?
